The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels.
It's competitively priced: Wood fuel can compete on fuel price with the fossil fuel alternatives, although the costs of installing wood fuel systems can be higher than fossil fuel systems.
On a steam raising boiler there are three clear applications for level monitoring devices:
1) Level control - To ensure that the right amount of water is added to the boiler at the right time.
From wood burning to pellet-firing biomass, alternative fuel boilers and solid fuel fired boilers offer environmentally friendly energy options and cost efficiencies. With the push to become less reliant on fossil fuels, alternative fuel boilers provide a way for plant managers to save money on fuel sources as well as meet tightening emission regulation standards.
If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur.
Carryover can be caused by two factors:
To prevent scale formation from low remaining levels of hardness which may have escaped treatment. Sodium phosphate is normally used for this, and causes the hardness to precipitate to the bottom of the boiler where it can be blown down.
